2007 Mercedes-Benz GL-Class brakes problems
severe 10 complaints filed with NHTSA · avg repair $450 · see brakes across all vehicles →
Among the 7 model years of Mercedes-Benz GL-Class in our records for brakes problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Owners report brakes that start acting up early—some as low as 5,000 miles. The most common complaint is excessive brake pedal travel, with the pedal sinking nearly to the floor and requiring heavy pressure to stop. One owner got a complete brake job at the dealer and the problem didn't go away; the dealer said it's normal. Another experienced a collision at 187,000 miles after brake failure, despite a recall notice (Campaign 22V315000) having been issued for the brake booster.
Several owners describe sudden brake loss during emergency stops: pedal goes mushy, brakes initially grab then release unexpectedly, and one independent mechanic suspected ABS sensor failure. In one low-speed snow incident, brakes locked and steering seized. Other owners report air getting into the brake lines with no clear cause, requiring a full system bleed and fluid replacement to restore function.
Premature wear is another pattern. At 36,000 miles on a well-maintained vehicle, all pads and front rotors needed replacement at once. One owner heard brake squeaking at 4,000 miles with longer stopping distances; the dealer ground the pad edges but didn't find the root cause. A few owners also report low brake fluid warnings triggering during hard braking even when fluid levels check normal.

Failure modes owners describe
Brake pedal excessive travel / low stopping power
Brake pedal travels too far (nearly to floor) during braking, requiring excessive pressure to stop. Often occurs early in ownership and persists even after complete brake service. Dealers typically claim this is normal.
When: As early as 5,000 miles; some cases reported at 20 mph, others on highway
Symptoms owners cite: Pedal travels excessively toward floor; Weak or delayed stopping response; Requires multiple brake applications to slow vehicle
Repairs/costs cited: Complete brake job performed in at least one case with no resolution; dealer stated condition is normal
Recalls/TSBs owners mention: NHTSA Campaign 22V315000 (Service Brake, Hydraulic) issued; recall notification sent but at least one dealer inspection found brake booster was not replaced as required
ABS sensor failure with brake lock-up and mushy pedal
Brake pedal becomes mushy and ineffective during emergency braking. Initial brake grab followed by sudden release suggests ABS sensor malfunction sending erroneous speed data to central computer, potentially disabling airbags and safety systems.
When: February 2008; no mileage stated for complaint #1
Symptoms owners cite: Mushy, ineffective brake pedal; Brakes grab initially then release unexpectedly; Loss of ABS function; Steering lock-up in low-speed snow conditions
Repairs/costs cited: Independent Mercedes mechanic suggested ABS sensor failure as cause; no factory inspection or parts replacement performed
Recalls/TSBs owners mention: Mercedes owner contacted manufacturer; no inspection or resolution offered
Soft brakes and air in brake lines
Brake pedal becomes soft and spongy with minimal stopping power. Air enters brake system without identifiable cause. Condition corrects after bleeding brakes and replacing brake fluid, but root cause remains unknown.
When: During highway driving; no specific mileage reported
Symptoms owners cite: Soft, spongy brake pedal; Minimal braking effect initially; Pedal requires pumping to regain control; Air detected in brake lines
Repairs/costs cited: Brakes bled and brake fluid replaced; function restored
Recalls/TSBs owners mention: Complaint references NHTSA Campaign 22V315000
Brake pad and rotor premature wear
Brake pads and rotors wear out prematurely even on well-maintained vehicles. At 36,000 miles, all brake pads and front rotors require replacement simultaneously with brake wear sensor activation, suggesting design or material defect.
When: 36,000 miles on well-maintained vehicle with scheduled dealer service
Symptoms owners cite: Brake wear warning message on console; All brake pads worn simultaneously; Front rotors damaged
Repairs/costs cited: Dealer replaced all pads and front rotors; questioned if brake sensor itself is defective
Brake squeaking and increased stopping distance
Brake pedal produces squeaking noise when depressed, accompanied by longer stopping distance. Dealer response was to grind or chamfer brake pad edges rather than identify root cause.
When: 4,000 miles; stopping distance increased by 6,600 miles
Symptoms owners cite: Squeaking noise on brake pedal application; Increased stopping distance
Repairs/costs cited: Dealer ground edges of brake pads and recommended chamfering; vehicle noted as low on oil
Low brake fluid warning without actual fluid loss
Low brake fluid warning light activates when braking firmly, despite brake fluid level being normal when checked. Braking response also becomes sluggish.
When: Recent weeks prior to complaint; timing unclear
Symptoms owners cite: Low brake fluid warning light illuminates during firm braking; Longer braking distance; Warning occurs despite normal fluid level
Recalls/TSBs owners mention: Owner uncertain if related to NHTSA Campaign 22V315000
ABS, ESP, and power steering system transient failure
Multiple vehicle systems (ABS, ESP, Parktronic, power steering) fail simultaneously during normal driving after making a left turn. Condition self-corrects after vehicle is restarted, but recurrence indicates a systemic electrical or control module issue.
When: Left turn from stop; no mileage stated
Symptoms owners cite: ABS system failure; ESP system failure; Parktronic system failure; Loss of power steering feel; No warning lights reported
